Can a 56 × 45 × 25 cm bag go under the seat?

No: it’s bigger than every published under-seat limit, the largest being 48 × 34 × 23 cm on Qantas. It has to go in the overhead bin.

Is a 56 × 45 × 25 cm bag free to take on board?

Free in every fare on British Airways and Jet2. On easyJet it’s a paid cabin bag: only a smaller under-seat bag is free. On Delta, Southwest, Alaska, Hawaiian, Batik Air, Cathay Pacific and Jetstar it’s over the carry-on limit and no under-seat size is published, so it’s free only if it fits under the seat in front of you. On American, United, JetBlue, Frontier, Allegiant, Sun Country, Breeze, Avelo, Ryanair, Wizz Air, AirAsia, Malaysia Airlines, Singapore Airlines, Scoot, Air Canada, WestJet, Qantas and Virgin Australia it’s too big for the cabin and would have to be checked.
